MEASURING-ROD.

SPECIFICATION forming part of Letters Patent No. 413,930, 'dated October29, 1889.

Application filed January 30, 1889. Serial No. 298,093. (No model.)Patented in Canada. December 17, 1888, No. 30,420.

measuring-rods; and it consists in certainnovel features hereinafterdescribed and claimed.

In the accompanying drawings, Figure lis an elevation ofmy completedevice eXtended. Fig. 2 is an edge View of the same. Figs. 3 and et areviews of `the device folded, taken at right angles to each other. Fig. 5is a detail View of the arm designed for use in measuring horses.

Referring to the drawings by letter, A designates the measuring-rod,consisting of the central or main section B and the end sections O D.The central section B is provided with the longitudinal slots E, and hasat its center the trammel-point F, which is secured permanently in thesaid section in any de; sired manner. The end sections O D are providedwith longitudinal slots G, through which pass the bolts H, which arepermanently secured in the ends of the central section B, and areprovided on their extremities with the thumb-nuts and washers I J, whichare adapted to bind against the sides of the end sections, so as toclamp the same to the central section at any desired point.

K designates screws or bolts, which are inserted through the slots E ofthe central section, and are secured permanently in the ends of the endsections. These bolts aid in guiding the end sections in their movementson the main section and holding the sections together.

L designates an arm, which is provided at one end with a bracket M,having doWel-pins N engaging the longitudinal slots G of the end sectionC, so as to guide the said bracket and arm when being adjusted upon theend section in adjusting the device. This bracket also carries a bolt O,which passes through the slot of the end section and islprovided with athumb-nut P, which is adapted to be turned home against the end section,so as to secure the said arm and bracket at the desired point. Thebracket and the arm L can be readily removed when not in use, so thatthe device will occupy but little room. The bracket is provided onv oneside with a plummet Q, so as to indicate when the said arm is level.

The several sections of the measuring-bar are provided or marked withthe scale of lineal measure, so that the length or other dimension ofthe object being measured can be readily seen. The end section D is alsoprovided in its end with a trammel marker or pencil, so that by reasonof the said marker and thetrammel-point F the device may be used todescribe circles. My device is intended for use in measuring heights ofobjects or in measuring Widths of door and Window openings and similarpurposes, and the desired measurement is ascertained by adjusting theseveral sections upon each other until the entire length of the rod isequal to the dimension desired, when the thumb-nuts are tightened, so asto hold the sections together until the measurement can be noted, whichis done by reading the scale marked on the sections, as will bereadilyunderstood.

The arm L is intended more-especially for use invmeasuring horses, andin use the end section carrying the said arm is adjusted so as to bringthe said arm upon the back of the horse, and when the plummetdndicatesthat the said arm is level the sections are secured together and theheight of the horse Will be indicated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A measuring-rod comprising the sections B C D, the central section Bhaving the longitudinal slots E, and the end sections C D having thelongitudinal slots G, the bolts H,

secured in the ends of section B and passing and the bolts K, insertedthrough the slot-s E roo in the central section B and into the innerends of the sections C D, as set forth.

2. The combination of the central section B, the end sections C D,secured thereto and longitudinally adjustable thereon, and the arm L,secured to and projecting laterally from the section C and adjustablealong the same, as set forth.

3. The combination of the central section B, the end sections C D,having the longitudinal slots G and adjustably secured to the centralsection, and the arm L, adj ustably secured to the section C andprovided with a bracket M, having pins N, engaging the slot G, as setforth.

4. The combination of the central section,

. the end sections adjustably secured thereto, the arm L, having' abracket at one end ad- Y WILLIAM DRISCOLL. 'Witnesses EDMUND F. BURRITT,D. J. IIURLEAN.
